METAL-FRAME VJ'INDOW.

Application filed May 11, 1911.

To all whom it may concern Be it known that we, W'ILLIAM D. VAT- soN andOKLA H. IMAN, both citizens of the United States, residing at Chicago,in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Metal-Frame Windows, of which the followingis a specification.

This invention relates to improvements in metal frame windows, and hasreference more particularly to improvements in that type of window whichhas come to be known to the trade as the fenestra type.

Among the salient objects of the invention are to provide a constructionin which the transoms and muntins are of sheet metal, as distinguishedfrom solid metal, but are nevertheless of such form and construction asto afford the requisite strength combined with the advantages of sheetmetal construction; to provide a construction in which is embodied atwo-part separable muntin-bar, one of the halves of which is fixed orstationary and the other removable, and these parts of such constructionthat when properly united they afford enormous strength, are adapted toaccommodate various thicknesses of glazing, and permit the glazing to beinserted and seated in structurally formed grooves in accordance with ageneral method practiced in this art; to provide a construction in whichthere are combined with the separable muntins cross-bars or transoms atright-angles to the muntins which are removable and may be set intoplace progressively as the glazing is inserted and serve to unite theproximate edges of the panes of glass in a simple, strong and extremelyeffective manner, and which at the same time cover a minimum area of theglass; and to provide an improved form of window construction whichlends itself readily to modifications in size by the simple addition ofmore units.

Our invention, its novel constructional features, its manner ofassembling, and the advantages inhering therein will all be readilyunderstood when considered in connection with the accompanying drawingswhich illustrate one practical embodiment thereof, and in which Figure 1is a side elevation, broken off at one side, of our improved window.Fig. 2

cent transoms. Fig. 3 is an enlarged central vertical sectiontransversely of the Windowframe through one of the muntins of the upperhalf of the window-frame, the same being broken out between its ends.Fig. 4 is an enlarged detail view in horizontal section through one ofthe muntin-bars, on the line H of Fig. 3. Fig. 5 is a detail view invertical section through the joint between one of the permanentmuntin-bars and the upper cross-bar of the jainb frame, as the samewould appear on the line 55 of Fig. 3. Fig. 6 is an enlarged detailview, in perspective, illustrating a structural feature of the upper andintermediate cross-bars and the manner of inserting the removablemuntinbars and the panes of glass. Fig. 7 is a top plan view of theupper cross-bar of the outer frame or jamb. Fig. 8 is a perspective viewof one of the continuous two-part muntinbars and two of the continuoustransom-bars, showing a portion of the glass in place.

Referring to the drawings, 10 designates the vertical and 11 and 12 theupper and lower horizontal members, respectively, of a rectangular jambframe adapted to be permanently set in the wall of a building. Themembers 10, 11 and 12 are hollow sheetmetal structures provided on theirinner sides with grooves or channels, such as 11 and 12 adapted to seatthe outer marginal portions of the glazing. The structure herein shownalso includes a central cross-bar 13 preferably formed, as best shown inFig. 2, by a mating-bar or bars, such as the upper jamb bars 11, setedge to edge, and united by internal cleats 14 secured to said bars asby screws 14?; said intermediate cross-bar 13 being provided in itsupper and lower sides with integral reentrant portions formingglass-receiving channels or grooves 13 and 13 The transverse frame bar13 thus divides the entire structure into a pair of upper and lowerduplicate sections. The sections thus formed are each subdivided bymuntins and transoms into a plurality of glazed panels depending, ofcourse, upon the number of muntins and transoms employed, whichlatter'is, of course, optional, and immaterial to the structuralfeatures involved in the present invention. We have herein shown eachsection as employing a pair of transoms and a pair of muntins, thuscreating in each section nine glazed panels. The

transoms, designated 15 are, as best shown in the sectional views, ofFigs. 2 and 3, of H- shape in cross-section, being formed of sheet-'metal pressed to the specified form; and the ends of these transomssimply enter the vertical glass-receiving grooves formed in the innersides of the vertical hollow jambs 10.

The muntins are of hollow sheet-metal construction, and each is atwo-part structure comprising an outer permanent section 16 and asimilar inner removable section 17 (Fig. 1). These sections preferablyhave the cross-sectional form illustrated in Figsn 4 and 7. The outersections 16 are permanently secured at their upper and lower ends in thecross-bars 11, 12, and 13 of the main frame; while the inner sections 17are re:

in which they are secured at their ends are of considerable length, itis desirable to provide intermediate connecting devices between theouter and inner bars of each pair; and for this purpose we employdirectly beneath each of the transoms 15 a connecting link 19 (Figs.3and 4), which is pivoted at 19 between the side walls of the muntinbar16 and, at its free end, extends across between the side walls of themuntin-bar 17, being provided at its free end with a slot 20 adapted toreceive a bolt 21 passed through said slot and also through slots 22 inthe sides of the muntin bars 17. Lying in said slot on the outer side ofthe bolt 21 is a wedge 23 that is forced inwardly by the nut 24: of thebolt 21, which wedge, by bearing against the outer end of the slot 20,has the effect of automatically forcing the removable muntin bars 17into snug engagement with, the adjacent side of the transom 15, thusclamping the latter snuglyupon the edge of the glazing.

In assembling the window in the outer or bounding jamb frame, thepermanent muntin bars 16 are first secured in place, after which thelower row of panes of glass 26 are set in proper position engaging thechannels of the uprights 10 and lower cross-bar 12. The lower transom 15is then put in place, the ends thereof entering the channels in theuprights 10. The next horizontal row of panes of glass is similarlysetin place, followed by the next cross-bar or transom 15. The upper rowof panes of glass is then positioned by inserting the upper edge of thefirst pane through a slotr27 inthe base.

of the lower channel of the central crossbar 13 (see Fig. 2), thenlowering the pane into the upper channel of the transom 15,

fill one of the outer side panels.

and then sliding it to one side or the other to The second pane issimilarly introduced and slid to theopposite side, while the third paneoccupies the intermediate panel. 1n the same way the several panes ofglass filling the panels of the upper section are successively intro-'*duced, the upper cross-bar 11 of the jamb I frame having a slot 28 (Fig.7) similar to and for the same purpose as the slot 27.

The several removable muntin bars 17 are then inserted 1n the mannershown in Ilg.

3 by first introducing their upper ends through the openings 18 intheupper and intermediate cross-bars 11 and 13, respectively, thenswinging their lower ends in-' wardly and dropping them through similaropenings in the upper sides of the cross-bars 13 and 12, said lower endsbeing stepped on rests 25 secured within said cross-bars, as clearlyshown in Figs. 2 and 3. The connecting links 19, when employed, areswung downwardly from the dotted line position; (Fig. 3) to thehorizontal positionjust prior to the introduction of each of thetransoms 15; and after the insertion of the removable muntin-bars 17,they are connected to the latter by the bolts 21 (and wedges 23, whenemployed), whereby the several parts of the complete window are unitedinto a strong and rigid structure. The purpose of pivot ing theconnecting links 19 is to be able to' swing said links upwardly out ofthe way when inserting the end panels of each horizontal row, thesepanels being inserted at the central opening and slid edgewise topermanent position.

The edges of the glazing panels which are engaged by the H-shapedtransom bars are,

snugly held, by the latter, especially where said transom bars areformed, as herein shown, of sheet metal folded and pressed to shape,since they are to a certain extent compressible upon the glazing by theconnecting and tightening links which unite the outer and inner muntinbars. The other edgesof,

the glazing panels have a more or less loose engagement when firstinserted with the,

channels formed in the muntins and side and cross-bars of thejamb-frame; and tight oints at these points may readily be se cured by apacking of putty, paint, or other suitable material, as indicated at29and as is well understood in the art. s WVe claim 1. In a sheet metalwindow construction,
